Ajax HomeSiren White Wireless Indoor Alarm Siren (Jeweller)

Ajax HomeSiren White - Wireless Indoor Alarm Siren

The Ajax HomeSiren is a compact wireless indoor siren built for residential and small commercial security systems. Designed to sit indoors and communicate with an Ajax hub over the long-range Jeweller radio protocol, it delivers a loud, adjustable audible alert whenever a connected detector is triggered, while also doubling as a status indicator for arming, disarming, and entry/exit delays. Its discreet white housing and small footprint make it easy to mount out of sight, helping deter intruders who might otherwise try to locate and disable a siren.

Key Features

• Adjustable volume: Sound output can be tuned from roughly 80 to 98 dB (up to 105 dB depending on firmware/region) at 1 metre, matching the siren to the size of the room.
• Long wireless range: Uses the Jeweller protocol to maintain a stable link with the hub or a range extender at distances of up to 2,000 metres in open space.
• Configurable alarm duration: Alert length can be set anywhere from 3 seconds to 3 minutes via the Ajax app.
• Status indication: Built-in LED shows arm/disarm state and can flag door openings, entry/exit delays, and after-alarm status.
• External LED connector: Supports an additional LED so status can be displayed in a separate, more visible location.
• Long battery life: Runs on two CR123A 3V batteries for up to 5 years, with battery status reported to the hub.
• Tamper protection: Detects attempts to open or remove the unit and instantly reports tampering to the system.
• Self-diagnostics: Continuously monitors its own tamper, communication, and power status and reports back to the hub automatically.
• Quick installation: Ships battery-installed and pairs to an Ajax hub in one step through the mobile app, with SmartBracket mounting for fast wall fitting.

Typical Use Cases

HomeSiren White suits homes, apartments, offices, and retail spaces already running an Ajax security system. It works well as a hallway or living-area alert that wakes occupants during an intrusion, fire, or leak alarm, and it can be configured to chime softly as an entry-delay reminder so users know to disarm the system before an alarm is raised. Because it is Ajax-hub dependent, it is intended purely as an add-on component within an existing Ajax Jeweller ecosystem rather than a standalone siren.
